Laser guided parking apparatus and method
This abstract describes an apparatus and method for accurately parking a vehicle within an enclosed space such as a garage. The apparatus uses a compact diode laser and is mounted directly to a ceiling or to a device mounted to the ceiling such as a garage door opener unit. When mounted above the vehicle the bright red laser lines are projected from the laser downward and aligned onto a specific surface for the driver to see such as the top surface of a vehicle dashboard. These lines intersect each other forming an ‘X’ (or ‘cross’). This ‘X’ can be aligned with either an existing dashboard feature or with a ‘target’ which is adhered to the dashboard. When a vehicle enters into a garage the first projected laser line that the driver will see will be the longitudinal line. The longitudinal line enables the driver to adjust the vehicle to the right or left as the vehicle continues into the garage. The second projected laser line appears laterally as the driver pulls forward to a stop. When this lateral line and longitudinal line align with the target or other specific location on the dashboard, the driver stops the vehicle. At this point the driver has positioned his vehicle exactly where he wants it to be within the garage.

Newcomer, This invention uses a ‘Guard Tube’ device to project two linear beams. This device is large, complex and antiquated.
In general these inventions do not combine simplicity, reliability, adjustability and compact design features along with the ability to project highly visible linear lines to accurately guide and position a vehicle to a pre-described location inside a garage or other similar structure. In addition, none of these inventions include a ‘target’ appliqué for use in aligning a vehicle.
SUMMARY OF THE INVENTIONAn object of the invention is to provide an apparatus and method for accurately and easily guiding a vehicle into a garage to a predetermined location.
A further object of the invention is to combine reliable ‘State-of-the-art’ compact diode laser technology with a mounting provision that is simple to install, adjust and utilize for parking a vehicle.
A further object of the invention is to provide an improved method for guiding a vehicle using highly visible linear lines which enable the driver to adjust the vehicle side to side and forward and rearward prior to stopping at a precise location.
A further object of the invention is to provide a means for aligning the ‘cross’ laser beams, such as a ‘target’ appliqué, made from a material that is highly reflective and visible to the driver when struck by the laser beam. This appliqué can be adhered to a surface such as a dashboard and positioned as required for easy view-ability by the driver.
The invention includes an apparatus and method and an article of manufacture for guiding a vehicle precisely into a predetermined parking location. More particularly the present invention relates to an apparatus composed of a currently available compact diode laser unit mounted to a holding device. The holding device (or holder) is designed to hold the laser unit. The holder fits into a base unit which in turn is mounted to the ceiling of the garage above the vehicle to be guided. The combination of laser, holder and base unit allows one to attach, adjust and focus the laser beams quickly, easily and accurately.
Additionally, as a means to activate the device ‘on’ and ‘off’, several options exist.
Option 1, allows the device to be plugged directly into an available electrical outlet provided by and integrated into the garage door opener. This outlet provides the required voltage to operate the laser and is coupled with the garage door opener light. Typically, when the garage door opener is activated to allow a vehicle to enter, the opener light also is activated. With this arrangement the garage door opener assures the parking laser goes on when it is needed and turns off automatically when the garage door opener light goes off.
Option 2, provides a motion detecting device which is combined with a low voltage transformer unit. These combined devices plug directly into the ceiling plug which is typically available for the garage door opener and located centrally on the ceiling. When a vehicle enters the garage the motion sensing (IR) switch will activate the laser unit and after a preset amount of time (several minutes) will turn off automatically. An optional power source can be batteries.
Option 3, uses a light detecting device which is combined with a low voltage transformer unit. These combined devices plug directly into the ceiling plug which is typically available for the garage door opener and located centrally. When a vehicle enters the garage, the light sensing (photovoltaic) switch will activate when it senses the light from the garage door opener. When the garage door opener light goes out, so will the laser. An optional power source can be batteries.
Option 4, provides a sound detecting device which is combined with a low voltage transformer unit. These combined devices plug directly into the ceiling plug which is typically available for the garage door opener and located centrally. When a vehicle enters the garage, the sound sensing (audio-activated) switch will activate when it hears the sound of the garage door opener. When the garage door opener closes and the garage becomes silent, the laser will turn off. An optional power source can be batteries.
The line generating diode laser unit and mounting system provides the user the advantage of mounting the base with either a single screw and/or adhesive tape. The laser holder mounts to the base by way of a fully articulating, (pivot and rotating) ball and socket design. Furthermore, the laser lines can be adjusted and focused to provide the best sharpness by turning the laser tip ring. Once the focus is set, the linear ‘X’ (or ‘cross’) pattern can be rotated (clocked) and positioned using the holder ‘rotation wheel’ and ‘ball and socket’ pivoting mechanisms.
The above objects and advantages of the invention are illustrative and not exhaustive of those which can be achieved by the invention. Thus, these and other objects and advantages of the invention will be apparent from the description herein, both as embodied herein and as modified in view of any variations which will be apparent to those skilled in the art.
Embodiments of the invention are explained in greater detail by way of drawings, where the same reference numerals refer to the same features.

Not shown but described later in this document are the sources for power and vehicle detection for this apparatus and method for guiding a vehicle to a precise location within a garage or other similar space.
The method of operation for this laser guiding system requires the laser apparatus be affixed to a location above the vehicle (such as the ceiling in a garage) just above a specific location such as the vehicle's dashboard. Once the laser is attached it may now be adjusted and focused on the prescribed location such as the center of the dashboard so that it is easily seen by the driver, see

Not shown but easily understood to those familiar with the art is the power and detection methods to provide the ‘on and off’ capabilities of this invention. Several options exist and are commercially available to apply power and ‘on/off’ control to the laser. An integrated battery pack can be used to power the unit along with either an IR (motion) or photovoltaic (light sensing) or audio sensing sensor that can switch the unit ‘on’ and after a prescribed duration (such as 1-5 minutes) turn the unit ‘off’ by way of a timing circuit. Another method can use a direct connection to the garage door opener. It is clearly understood that most modern garages use an electric garage door opener to open and close the garage door. It is also understood that the mechanism for opening the door is located near the garage ceiling either centrally or near the top of the main garage door. It is also known that such door opening devices have a courtesy light that is activated when the door opens and turns off automatically after a prescribed amount of time, i.e. 1-5 minutes. That said, the compact laser device could, for instance, be plugged directly into this device to acquire both power and ‘on and off’ control. Furthermore, the compact laser device could be incorporated as an integral part of the garage door opener unit supplying the power.
